Favor bags: I'm usually a fan of practical favors, but it was hard to resist so many crazy cute Disney things at the party store. Each kid got a Disney Pez dispenser (assorted characters!), pencil, stickers, popping candy, and a Disney Dance Party cd for each family.

I knew I put the right person in charge of balloons: I never would have thought of decorating the bannister, it looked terrific!

My favorite decor: a collection of vintage-y mini posters of all Clark's favorite attractions from Disneyland last year.

Balloon girl also helped run the party – she and her good friend ushered all the kids downstairs and helped them with party games (character cake walk, freeze dance, Bingo and Mad Libs).
